Claims14
An implant for osteosynthesis comprising a biocompatible device for attachment to a bone, and a plurality of screws for attaching the device to the bone, the heads of said screws and the device having a predetermined friction angle relative to one another, said screws having conical heads and said device having complementary conical holes for receiving said heads in surface contact therewith, the cone angle of the conical holes being less than the friction angle between the holes and the screw head, thereby locking said screws to said device to prevent said device from sliding down the screw heads.
